ABSTRACT

A freestanding mixed martial arts training device includes vertically connected first and second posts, a base stand connected to a lower end of the first post, a water containable pedestal assembly, and primary and secondary striking pads as well as kick training plates height-adjustably mounted to the first and second posts. The first and second posts can be supported in a freestanding state by the base stand with a plurality of suction cup assemblies mounted thereto, or by the pedestal assembly fitted around the base stand without using the suction cup assemblies. The first post is also connected to the base stand via a plurality of screws, so that striking forces applied to the first and second posts can be evenly distributed to the screws without causing a broken and leaking pedestal assembly due to stress concentration thereat. Therefore, the mixed martial arts training device is more practical for use.

FIELD OF THE INVENTION

The present invention relates to a knockdown freestanding mixed martialarts training device, which can be differently assembled to suit fordifferent users' training requirements, and has the advantages of lightweight, reduced overall volume and durable for use.

BACKGROUND OF THE INVENTION

Most of the currently available martial arts training devices, such asthose disclosed in U.S. Pat. No. 5,624,358, U.S. Pat. No. 6,027,435,U.S. Pat. No. 6,790,167 and U.S. Pat. No. 7,086,997, due to thestructural designs and assembling manners thereof, are subjected tostress concentration at a joint or a contact surface between awater-containing pedestal and a post of the training devices andtherefore tend to have a broken and leaking pedestal after having beenused over a period of time. U.S. Pat. No. 5,624,358 discloses a trainingbag apparatus, which includes integrally connected post andwater-containing pedestal, and therefore encounters the problems ofhaving easily leaked pedestal due to stress concentration, being bulkyin volume to increase transport and storage costs, and having a postthat can not be adjusted in height to satisfy different users. WhileU.S. Pat. No. 6,027,435 discloses a height-adjustable freestandingtraining bag, it still has a water-containing pedestal integrallyconnected to a post and therefore can not solve the problem of having abulky volume. While U.S. Pat. No. 6,790,167 discloses aheight-adjustable striking bag training apparatus that has a pedestalformed of several detachably assembled pedestal parts to enable areduced storage volume, it does not allow different striking trainingmeans or parts to changefully mount to the post thereof and thereforeprovides only simple function and is monotonous for use withoutsatisfying different users. U.S. Pat. No. 7,086,997 discloses a martialarts practice device that allows changeful mounting of differentstriking training parts to a post thereof but is not adjustable inheight and has a pedestal fixedly connected to the post. Anotherdisadvantage of the martial arts practice device disclosed in U.S. Pat.No. 7,086,997 is the high material cost thereof that does not meetusers' economical requirement.

SUMMARY OF THE INVENTION

In view of the drawbacks in the conventional martial arts trainingdevices, a primary object of the present invention is to provide animproved freestanding mixed martial arts training device that has astructural design avoiding stress concentration and is therefore moredurable for use.

Another object of the present invention is to provide a knock-downfreestanding mixed martial arts training device that can be freelyassembled in different manners according to actual trainingrequirements, and can be disassembled to occupy only a very small spaceand can therefore be conveniently transported and stored at reducedcosts.

A further object of the present invention is to provide a freestandingmixed martial arts training device that includes a height adjustablepost provided with structures for different striking or kicking trainingcomponents to be conveniently but firmly connected thereto while thepositions and heights of these components are freely adjustableaccording to actual need in training.

A still further object of the present invention is to provide a mixedmartial arts training device that allows a user to select different waysfor supporting the training device in a freestanding state, so that thetraining device can be used in different training places to meet theuser's economical requirement.

To achieve the above and other objects, the freestanding mixed martialarts training device according to an embodiment of the present inventionincludes vertically connected first and second posts, a base standconnected to a lower end of the first post, a water containable pedestalassembly, and primary and secondary striking pads as well as kicktraining plates height-adjustably mounted to the first and second posts.The first and second posts can be supported in a freestanding state bythe base stand with a plurality of suction cup assemblies mountedthereto, or by the pedestal assembly fitted around the base standwithout using the suction cup assemblies. The first post is alsoconnected to the base stand via a plurality of screws, so that strikingforces applied to the first and second posts can be evenly distributedto the screws without causing a broken and leaking pedestal assembly dueto stress concentration thereat. Therefore, the freestanding mixedmartial arts training device of the present invention is more practicalfor use.
